Ive tested both, and the 5 a week seemed to be seriously counter productive for me. Now I am on a LR question (chapter in LR bible) type a day, example: 60 assumption questions in a row.... and a timed LG section every day. Every day a new LR type goes bye a new flash card is done up with all the important notes about that type and I review those daily. I have never had a problem with time however so this is more productive for me, for some odd reason I always end at 35 minutes heh, So I do one timed preptest a week on Friday. This will be increased only in the last week which will be 5 section preps timed, 4 times a week.

In only did one actual full length test a week. I used the older tests for practicing individual sections, and the newer ones's for the full length tests. The last two weeks before the test, I bumped it up to three a week. 5 is just too much. You don't want to burn yourself out. The secret to improving your LSAT score isn't just doing tests, you have to review them over and over again to see what you're doing right and what you're doing wrong.
